CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external

A World Without Friction (603 Words)Although friction may seem like a minor issue‚ its absence would chance life as we know it. There would be many negative effects of this like not being able to gain traction on any surface and your ipods earplugs always falling out. Also‚ there would be many positive effects‚ such as eliminating the need for coolant in engines and lubricant in machines. Moreover‚ the absence of friction would be both bad and good. Without friction‚ many obvious things which we

To know how rotameter works. INTRODUCTION The measurement of fluid flow is important in applications ranging from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. The selection of the proper instrument for a particular application is governed by many variables‚ including

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all the time

Fluid and Electrolytes Imbalances Fluid Compartments: * Extracellular Fluid (ECF) – This is fluid found outside of the cells and the amount of ECF decreases with age. In the newborn for example‚ approximately ½ of the body fluid is contained in the ECF. By the time the infant has reached one year old; the ECF has decreased to approximately 1/3 of the total volume. In an average 70 kg adult the ECF is approximately 15 liters of total volume. ECF can further be divided into the following:

Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar

Drunk driving “Please blow into this machine. Thank you.” If you are a driver‚ this sentence is familiar to you. Many police examine drunk driving at the crossroads every day. Meanwhile‚ numbers of advertisements and messages on TVs and radios persuade us not to drive after drinking. Driving without drinking has become a common understanding. But why do we have to accept this? And what would we do if somebody is drunk driving? Today‚ I hope to convince you that drunk driving is terrible and that
